Cruise Lines Offering Future Cruise Credits

Two carnival ships due into Galveston, Texas, Saturday are now headed to New Orleans to pick up more food, fuel and supplies.

More than 15,000 people aboard three Carnival Cruise Line ships scheduled to return to Galveston this weekend face delays or detours due to Hurricane Harvey in the Gulf of Mexico. The Port of Galveston was closed Friday amid the hurricane threat.

Carnival said they would give future cruise credits to anyone who chooses not to sail.

The Carnival Valor and Carnival Freedom will make a brief stop, where passengers can choose to end their cruise, but are being asked to stay onboard and sail back to Galveston once the port reopens.

Even after the storm passes, the port has to be inspected to make sure ships can safely get in and out.

A third Carnival ship, Breeze, was scheduled to return to Galveston on Sunday. It's spending Friday night in Cozumel, Mexico. That ship has more than 6,000 on board. The Carnival statement said the ship would depart Saturday for Texas to be in position when the Port of Galveston reopens.

Royal Caribbean said its Texas-based ship, Liberty of the Seas will stay safely behind the storm for now.

"Liberty of the Seas is keeping a safe distance behind the storm as she making her way back to Galveston. We are actively monitoring path and progression of Hurricane Harvey and will make sure to inform our guests of any itinerary changes," the company said.

Liberty of the Seas isn't set to arrive in Galveston until Sunday, so they will have time to make a decision on its fate after landfall.

The Port of Galveston is shut down and passengers are asked not to drive to the port until it is reopened.
